The suspect in the Trader Joe's hostage situation is now in custody, police say.

Police believe a man involved in a standoff with officers at a Los Angeles supermarket had shot his grandmother and girlfriend before firing at officers during a pursuit, then crashing outside the supermarket and running inside the store.

Officer Mike Lopez, a police spokesman, says the man had fled from the scene after the Saturday afternoon shooting in South Los Angeles.

He says officers tried to pull the man over and were led on a pursuit. Lopez says the suspect shot multiple rounds at officers during the chase but no officers were struck.

At least one officer returned fire.

Lopez says the man crashed outside of a Trader Joe's supermarket in Silver Lake and then ran into the store.

Video footage at the scene shows several hostages have left the Trader Joe's store at Silver Lake, walking out with their hands up.

UPDATE: SWAT resources are on scene at the #traderjoes in #Silverlake as we work to bring a swift resolution to this incident. Again, this is an active and evolving situation, and we continue to urge the public and media to stay clear of the area.

Los Angeles Fire Department spokeswoman Margaret Stewart told CNN a 20-year-old female patient had been taken to hospital in a fair condition. She was removed from a vehicle, not the inside of the store.

"We are on standby and prepared to support but no confirmation how many patients may be inside," Stewart added.

CBS reported that police on scene say the man may be holding as many as 30 people hostage inside the store. Firefighters are preparing to treat multiple patients, but say they are still unsure how many there are.
